The cover plate 34 has a through hole 34a through which the rotating shaft 10a can penetrate, and the inner diameter of the through hole 34a is larger than the radial inner diameter of the rotating shaft 10a. The cover plate 34 is made of a transparent material so that the light generated by the light source 33a can pass through it and emit out.

[0044] A circular through hole perpendicular to its plane penetrates through the center of the panel 40, denoted as the matching hole 40a. At the matching hole 40a on one side of the panel 40, there is a tubular structure perpendicular to its plane, denoted as the embedding portion 40b.

The end face 52b is recessed in the gripping portion 52, and a triangular indicating mark 52c is integrally formed and protrudes in the end face 52b.

[0050] The knob 50 also has a clamping hole 50a that penetrates through the rotating part 51 and the gripping part 52 along the central axis of the rotating part 51. The radial cross-section of the clamping hole 50a and the rotating shaft 10a is a polygon that matches each other, so that the end of the rotating shaft 10a can be fittingly embedded in the clamping hole 50a. The knob 50 can be fixed to the end of the rotating shaft 10a by a bolt that passes through the clamping hole 50a and is screwed into the internal thread hole 10b.

[0051] The shape of the indicator board 60 is fittingly clamped with the recessed end face 52b in a groove structure and the indicating mark 52c. In this embodiment, the indicator board 60 is a transparent plastic board with any replaceable color.

The indicator board 60 is clamped at the end face 52b of the gripping part 52.

[0054] S20, the light generated by the light source 33a on the light source board 33 passes through the cover plate 34 and then irradiates out through the end face 52b of the gripping part 52.

[0055] S30, when the operator operates the gripping part 52 to rotate, so as to drive the rotating shaft 10a to rotate to adjust the opening and closing state of the change-over switch 10, a clear indication can be obtained through the light on the end face 52b.

[0056] S40, when the light source 33a on the light source board 33 is damaged, unscrew the bolt in the clamping hole 50a, and the fixed relationship between the knob 50 and the rotating shaft 10a can be released. Subsequently, pull out the knob 50 and the panel 40 in sequence, and pull out the light source assembly 30 embedded in the housing 20. Then, disassemble the light source assembly 30, replace the light source board 33 with the damaged light source 33a, and then snap the light source assembly 30, the panel 40, and the knob 50 back to the initial state in sequence. After using bolts to fix the knob 50 and the rotating shaft 10a and covering the indicator board 60, the switch device 100 can be used continuously.
